To G/ZZ whom it may concern.- 7

Be it known that I, HENRY F. DETERDING; a citizen of the United States, residing at Com-f merce, in the county of Scott-and State of Mis; souri, have invented certain new and useful Improvements in Tricycle Land-Rollers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to land-rollers, and comprises, essentially, a rear frame, to which frame roller-carrying frames are pivotally connected, so that different sets of rollers may be permitted to swing or oscillate with relation tothe rear frame in the practical use of the device.

In the process of breaking up land for cultivation it is impracticable to cause plows to run so true that there is not a variation in the depth and width of the furrows made, and the consequence is that an uneven surface of plowed ground results, composed of ridges and depressions. The common practice is to level the plowed ground by the use of a harrow or similar implement, which is scraped thereover in order to smooth it and'fill up the depressions. The ground is then rolled by the use of a roller having its axis'journaled in a fixed frame. In such method of procedure the roller fails to operate with uniform action on the ground composed of the ridges and depressions between them referred to. The roller presses upon the ridges and renders them more compact than before, while it fails to operate upon the depressions between the ridges and they receive no benefit from the rolling action.

In line with the foregoing it is the object of this invention to so improve the construction of a land-roller that it will contain independent sections that are capable of adjusting themselves to the inequalities of the land being rolled, and thereby equalize the weight of the rollerover the entire surface traversed to secure the essential benefits and bring positive results by acting upon all of the soil alike.

Figure I is a perspectiveview of my improved roller. Fig. II is a View in side elevation. Fig. III is-a face view of one of the individual rollers. Fig. IV is a detail view,

part in section, showing-the pivotal connec- 1 designatesthe tongue of the roller, provided with a clip 2, adapted to receive the doubletree, which is secured bya pivot-pin 2.

3 designates the frame of the forward set of rollers, having front and rear superposed cross-bars 3, the said frame being connected to the tongue 1 by a channel-plate 1, secured to its front cross-bar and also to the bracebars 4.

5 designates the individual rollers of the forward set, mounted on an axle (not seen) common to all of them, which axle is mounted in journal-boxes 6, carried by the frame 3. The journal-boxes 6 are closed at their outer ends and provided with oil holes or cups, that are protected by hinged covers 7. (See Fig. V.)

'8 designates a shield on the journal box adapted to project over the hubs of the outer rollers in such a manner as to' exclude dust from entering the bearings thereof.

6 represents bearing-blocks for the journal-boxes 6, secured with the shields 8 to the frame 3 by bolts 8.

It will be seen that the oil-holes in the j our nal-boxes 6 are located at the outer ends of theboxes as near as possible to such ends, which, as stated, are closed to exclude dust. By so locating the oil-holes I am enabled to introduce oil at the extreme outer end of the journals, so that it may be conveyed in the journals inwardly, and thereby carry or work through the open inner ends, of the journalbox any dust or dirt that may gain access to the journal at the open inner end. By this means the dust or dirt may be constantly worked. out of the journal instead of being allowed to remain therein.

Mounted on the rear cross-bar of the frame 3 are a pair of clip-jawsi), thatcontain a pivot-pin 10. These jaws are adapted to. receive the forward end of a reach 11, extending from the cross-bars 12 of the rear frame of the rear sets of rollers. A limited amount of space is provided between the clip-jaws 9 vided with journal-boxes 18.

(see particularly Fig. II) for the purpose of permitting fre'e oscilation and lateral motion of the roller-carrying frame 3 in the practical use of the machine.

The cross-bars 12 are arranged parallel to each other and are connected at their central portions by a channel-bar l3 and a weighttray 1t, the channel-bar being connected to the reach 11. The weight-tray ll serves as a receptacle for tools or objects that may be put therein to increase the weight of the main frame on the rollers.

15 designates shackles, pivoted to the ends of the cross bars 12 by bolts 16. These shackles are connected to rocking frames 17, havingcrossbarsfi. The frames 17 are pro- (Shown in detail in Fig. VI.) Each of these journal-boxes 18 is provided with an oil hole or cup, protected by a hinged cover 19 and a shield 20, adapted to extend under the journal-box 1S and over the hubs of the outer individual rollers 21, mounted within the frames 17 011 suitable axles (not seen) journaled in the boxes 18.

18 represents pendent bearing-blocks for the journal-boxes 18, seen red with the shields 20 to the under side of the frames 17 by means of bolts 20.

22 designates a seat the bifurcated support 23 of which is connected to the reach 11 and is provided with a foot-rest 24.

In the practical use of this roller the forward set of rollers 5 are permitted to partake of alimiteil amount of oscillatory motion by reason of the loose connection between the reach 11 and the clip-jaws 9, and at the same time the rollers 21 are drawn along the ground and oscillate with their carrying-frames 17, according to any unevenness of the ground, each frame 17 swinging on the pivot-pins 16 contained by the ends of the crossbars 12 and the shackles 15. In this manner the different sets of rollers 5 and 21 move into any depressions in the ground as well as travel on the high places, and thereby exert a uniform pressure over the entire surface traversed.

The end rollers 5 and 21 of each set are preferably loosely mounted on their shafts in order to facilitate their movement in turning from a straight line oftravel, while the central rollers may be keyed to the shafts.

The rollers may be of any desired exterior configuration. In Figs. Iand II,I have shown them with plain surfaces, while in Fig. III, I have shown a roller (designated by 5 pro vided with circumferential ribs 5", this latter form being valuable in that the ribs form clod breakers or cutters. The rollers may, however, be formed with transverse ribsor have surfaces of any other desirable form.
